I am having a problem with my Postfix > Dovecot installation. I have used webmin to administer with mostly defaults. The problem I am having is this:
When I migrated their old cpanel backups, it put all their waiting mail in a file called /firstname.lastname@example.org
Dovecot is working fine with this, I can access webmail and also pop mail from this box.
However, postfix is delivering all new mail to a file called /var/mail/username-domain.com. Thus its not getting received by the users.
In virtual domains under the postfix configuration in webmin, I can see the translation of email@example.com -----> username-domain.com but if I try to edit this to firstname.lastname@example.org---->email@example.com or just delete this mapping period, postfix bounces the mail back to sender with "username" is not on this server.
Thanks for any help in advance,
